IMPRovEMnNT '1N WASH-Bomans.

v.IlhoSchedule referred' to in these Letters Patent and making parl: ofthe same.

To all whom it may concern Be it known that I, S; A. Goonwrn, oflthe city of- Buflalo, vin the State of New York, have invented 'an Improvement in Wash-Boilers; and I do hereby declare that the following isa full and exact description thereof, reference being had to the accompanying draw# ings, and to thev letters of reference-markedthereon.

This invention relates to the class of wash-boilers in which the washingfwater, or alkaline-solution, is car-v ried up, by the force of vheatvor steam, from achamber under the clothes, through a tube or tubes, to the top of the boiler, and discharged upon and over the clothes, and allowed, by specic gravity, to percolate through them to the said chamberto be again forced up, in the same manner, 'in a continuous circulation. 4

The substantial partof this invention is -the discov-` ery` and application of a new or additional element', principle, or method in this processato wit, the separation from the solution of'the 'insoluble parts of the dirtpdischarged fromrthe clothes, by lltration, autov mati'cally,'at some point or points on the line of circulation. This object is accomplished by a mode ofcon struction and arrangement of parts whereby advantage is taken i' of the circulation of the solution to pass' it through` a iilter, that it` maybe iilte'red automatically, and without labor. l 'i To enableothers skilled inthe art to make and use my invention, I will proceed to describe it, with referl ence tothe drawings, in-which-`.

yliigureI represents a vertical longitudinal section of `aboiler, with myimprovements.

Figure II, a Inodiiicationfof' the same.' A is a portable wash-boiler, of the usual oblong form.

D Dare inclined plates, covering the bottom of the boiler, and forming, in connection with the bottomand with the hoop or rim g, a chambeiyin which the ysteam is generated, Y y B is a plate, extending across the boiler'transversely, and ibrming, in onnection .with D D, triangular-shaped chambers E E, for the filtering-substance.

The end. of D is bent'up, and attached to B, having apertures or perforations j. bf are bars, extending vacross the hoop g, for the 'support and drainage of the clothes. v

.O-C are tubes, connecting the chamber below the clothes with space above them. Sponge, or othersuitable filtering-substance, is placed ,in the chambers E E.

' The operation is as follows: Whenthe washing-solution is placed in the boiler, and the clothes are evenly by means of gauze within the by means of'a cloth diaphragmextending across the boiler.

spread -upon the bars b andv plates the boiler is then placed upon thev stove, and, steam being genel rated in the chamber under the plates D D, the water,

mixed with steam,is forced up the tubes C, and falls on'l to and over-the clothes, and percolates through them, and through the bars t', and through the filter,

-inthe direction of the arrows, through theJ perforation- F, into the chamber from which it started, when it is again forced up the tubes C, ina continuous circular tion. It is apparent that each time the water passes entering or going through the last. This may be done.

l by making small apertures, on opposite sides, in the rim or hoop g. l

Eig. II is a modicatic'n of Fig. I, and differs from it in having the plates D D Vinclined toward thev centre of theboiler, instead of toward the sides', and the cor-- responding change of position of the ltering-chamber, and having'one tube in the middle of the boiler, instead of one at each end. p

This improvement may be applied to any formof boiler, whether portable or stationary, of the class referred to, and maybe found valuable for washing. other articles, as well as clothes.V j v I do not limit myself to the particular mode of con- 'struction above described, for itis evident that this invention can be applied in'various ways, without any essential change.

I am aware that iiltration has been accomplished tube or pipe, and also l What I claim as my invention, and desire. to secure byv Letters Patent, is'- f l l. In connection with wash-boilers of the class above mentioned, the filtration of the washing-water automatically, as herein setforth.

2; The inclined imperforated plates D, bars b', plates B, and rim' .recombined together, and arranged with theboiler A and pipe or pipes C, substantially as and v for the purpose described.
